Geometry

2. two angles whose sides form two pairs of opposite rays
4. when all interior angles of a polygon are congruent
8. unproven statement that is based on observations
9. transformation in which a figure is turned about a fixed point
10. line that intersects two or more coplanar lines at different points
13. consists of an endpoint and an arrow at the other end
14. has two dimensions and looks like a floor/wall and extends without end
15. lines, segments, or angles that have the same measure
16. the ratio of vertical change to horizontal change
17. represented with an arrow at each end and extends without end
18. point, ray, line, segment, or plane that intersects at the midpoint
19. consists of endpoints and all points in-between
24. two lines that intersect to form a right angle
25. Process that includes looking for patterns, making observations, and forming conjectures
26. angle that measures greater than 90 degrees
27. transformation that uses a line to create a mirror image of a figure

1. two lines that do not intersect and are coplanar
3. transformation that moves every point of a figure that same distance in the same direction
5. angles or segments that occupy the same position
6. type of triangle where two sides are congruent
7. when all sides of a polygon are congruent
9. three sided polygon with a 90 degree angle
11. Rigid motions (isometry) that maintains angle measure and side length after moving a figure
12. lines that do not intersect and are not coplanar
17. two adjacent angles where their sum is 180 degrees
20. point that divides a segment in to two congruent segments
21. angle that measures less than 90 degrees
22. when no side of a triangle are the same length
23. Using facts, definitions, accepted properties, and laws of logic to form an argument
